Why does the Vancouver island marmot only live in Canada?

The Vancouver Island marmot is endemic to Canada, specifically found only on Vancouver Island, due to its specialized habitat requirements and evolutionary history. This species thrives in the island's distinctive mountainous and subalpine environments, which provide the necessary food sources and shelter. Additionally, geographic isolation has limited its distribution and led to distinct adaptations, making it unable to thrive in other regions. Conservation efforts are focused on preserving its habitat to prevent further decline.
